Providers build several RTP settings into every slot. The number you see on review sites is the maximum - not what the casino has configured. We open each slot on a real account in real-money mode and read the actual figure from the in-game paytable.
No simulation. No estimates. We open every slot on a real account in real-money mode and read the RTP from the in-game paytable.
We use a real registered account. Demo mode can show a different RTP variant. Real-money mode shows what the casino has actually configured.
Every slot has an info screen showing the current configured RTP. We record that exact figure - not the max the provider publishes on their site.
We pull the provider's published maximum RTP and subtract the actual figure. Casinos that hide the RTP completely get flagged separately.
We opened real accounts at all four casinos and tested every tracked slot their lobbies carried. Here is what we found.
5.8/10
10 of the 11 readable slots at Pistolo ran below the published maximum, and 4 games refused to show any RTP figure at all. The worst gaps were on Hacksaw Gaming titles - Le Fisherman and Dorks of the Deep both came in 3.99pp below the provider's stated max.
7.9/10
Wild Tokyo showed the RTP on every slot we tested. 6 of 15 ran at the exact published maximum. The worst gap was 3.00pp on Merge Up - a slot Wintino runs at full. No hidden figures, though.
5.6/10
The best average in our database at 94.93%, with 3 slots at the full provider maximum - Merge Up runs at 97.25% here versus 94.25% at Wild Tokyo. But 3 slots hide their RTP, and the casino names no licence, no operator and no jurisdiction anywhere.
6.2/10
The new best average in our database at 94.97%, and every launched game exposed a readable figure - Coin Flynn Deluxe runs at the full 97.00%. But real play is locked until you deposit, 11 of 14 slots run reduced variants, and the lobby tiles advertise the maximum while the session serves less.
Two bars per slot. The lighter bar is the published maximum. The coloured bar is what the casino is actually running. Green = at max. Amber = 1-2pp below. Red = 3pp+ below.
Le Fisherman at Pistolo. Published max: 96.33%. Actual: 92.34%. That gap costs a €1 spin player roughly €1.50 extra per 100 spins.
4 of 15 slots at Pistolo and 3 of 12 at Wintino showed no RTP at all. You cannot check what you cannot see. We flag every hidden RTP.
6 of 15 Wild Tokyo slots ran at the exact published maximum, and 0 RTPs were hidden. GreatSlots also delivered a full sheet - 14 of 14 readable, 3 at max.
Understanding RTP takes 10 minutes. Probably the most useful 10 minutes before gambling online.
The clearest explanation of Return to Player you will find. What it means, what it does not mean, and why the number on the casino site is often not the real one.
Providers build multiple RTP variants into every slot. Casinos choose which one to run. This guide explains exactly how that works.
A step-by-step walkthrough showing you how to find the configured RTP inside any slot in under 60 seconds. Most players never do this.
We test at real casinos, on real accounts, in real-money mode. There is no shortcut. Demo mode can show a different RTP variant, so we never record from it.
We record the RTP from the in-game paytable only. We do not estimate, simulate, or extrapolate. The figure we report is the one the slot shows you when you open the game info screen.
We have no commercial agreements with any casino. Affiliate links fund the testing. But the testing comes first - and if the numbers are bad, we say so. Pistolo's data makes that clear.
Marcus built CasinoWinRate because no review site was reporting the actual configured RTP - only the published maximum. He tests slot RTP configurations at online casinos and publishes what he finds. Read more
Every test is done on a registered real-money account. Demo mode is never used for RTP recording.
We read the RTP from inside the slot itself - the same screen any player can access.
Every reading includes the date it was taken. Casinos can change RTP variants at any time.
No casino can ask us to change a score. The data is what the data is.
